This basic shape reminds me of one of the developmental images that Matt Jefferies did that became the basis for the "final" version of the Enterprise
. I had long assumed that the Constitution-class was predated by earlier cruiser classes that formed an evolutionary chain, with each preceding class being less technologically advanced and of a less-evolved shape than later ones.
"The way that you wander is the way that you choose. / The day that you tarry is the day that you lose. / Sunshine or thunder, a man will always wonder / Where the fair wind blows ..."
